Kids will do as you do, not as you say.
If you teach your kids that it is an appropriate response to hit someone when they do something you don't like, that's a bad lesson and not practical in the adult world.
In my experience, the kids who got physically punished at home were always more likely to be violent towards their peers.
Instead, use the civilized adult-world justice system; fuck up and you get your freedoms taken away.. your property confiscated.. etc. Prolonged punishments that have a real impact on the quality of their lives. That teaches long-term consequences.
Otherwise, if you need to up the penalties, what are you going to do? Yell louder..? Hit harder...? It starts getting very white trash.
